Minimally invasive puncture with twist intraosseous drill needle combined with hematoma drainage in the treatment of acute epidural hematoma in pediatric patients: A technical note

OBJECTIVE

The current neurosurgical intervention for treatment of acute epidural hematoma (AEDH) usually involves a craniotomy. Despite its effectiveness, open surgical decompression has several limitations. The twist intraosseous drill needle (TIDN) is considered a feasible alternative in adult patients with AEDH. AEDH treatment with TIDN in pediatric patients has not yet been described. The study aimed to report the efficacy and safety of minimally invasive puncture with a TIDN combined with hematoma drainage for the treatment of AEDH in pediatric patients.

METHODS

We retrospectively collected medical records of children with AEDH who underwent TIDN surgery at our institution from January 2017 to May 2021, and analyzed their clinical and imaging results. A detailed step-by-step surgical guide was provided.

RESULTS

Three pediatric patients with AEDH received TIDN treatment (including two males and one female; average age 7.66 years, range from 5 to 11 years). There were no intraoperative or postoperative complications in any case; 1 day after the operation, the AEDH was cleared in one of the three patients, and a slight hematoma remained in two patients. The remaining hematoma was evacuated after injecting urokinase into the hematoma cavity during indwelling drainage.

CONCLUSION

For pediatric patients with AEDH in a stable condition with a clear consciousness, TIDN puncture combined with hematoma drainage is safe, effective, and less invasive, and may present a viable surgical alternative option.

Twist-Drill or Burr Hole Craniostomy for Draining Chronic Subdural Hematomas: How to Choose It for Chronic Subdural Hematoma Drainage

Objective

Although twist-drill craniostomy (TDC) has a number of procedural advantages and an equivalent outcome compared to burr hole craniostomy (BHC) for the treatment of chronic subdural hematomas (CSDHs), the latter technique remains the preferred method. We analyzed symptomatic CSDHs in whom TDC at the pre-coronal suture entry point (PCSEP) was the primary method for hematoma drainage and BHC on the parietal was the secondary option.

Methods

CSDHs in 86 consecutive patients were included. TDC at the PCSEP, which is 1 cm anterior to coronal suture at the level of the superior temporal line, was the primary operational technique when the hematoma thickness was suitable, and BHC was performed via the parietal when TDC was unreasonable or failed. The clinical feasibility and outcomes of these approaches were analyzed.

Results

Of the 86 patients, 68 (79.1%) were treated by TDC, and 18 (20.9%) by BHC. All patients showed improvements in their symptoms after hematoma drainage. Neither morbidity nor mortality was associated with either technique, and there were no differences in drainage days between the groups. Ten patients had bilateral hematomas and were treated using TDC. Two patients were not sufficiently treated by TDC and, as a result, BHC was applied. Only six hematomas (7% of 86 hematomas) exhibited insufficient thickness on the computed tomography to perform TDC.

Conclusion

When the hematoma was thick enough, a majority of the CSDHs were drained using TDC at the PCSEP as the first procedure, which was especially useful for bilateral hematomas and in elderly patients.

Prognostic factors of clinical outcome after neuronavigation-assisted hematoma drainage in patients with spontaneous intracerebral hemorrhage

OBJECTIVE

The prognostic factors that contribute to outcome after navigation-assisted drainage in patients with spontaneous intracerebral hemorrhage (ICH) have not been defined. We compared the characteristics and clinical outcomes of patients with spontaneous ICHs who underwent neuronavigation-assisted hematoma drainage.

METHODS

Forty-seven patients were enrolled from January 2004 to August 2013. The patients were divided into two groups according to Glasgow Outcome Scale (GOS) scores: the good- (GOS 4-5) and poor-outcome (GOS 1-3) groups. A variety of factors, characteristics, and clinical outcomes were analyzed.

RESULTS

Among the 47 patients, 16 and 31 showed good and poor outcomes, respectively. The mortality rate was 4.3%. Patients' ages, horizontal and vertical diameters and volume of the hematoma on the initial brain computed tomography scan, and the initial Glasgow Coma Scale (GCS) scores were significantly different between the two groups (P<0.05). Ages less than 60 years, smaller horizontal and vertical diameters of the hematoma, less initial hematoma volume, higher initial GCS scores, and the absence of intraventricular hemorrhages were significantly associated with good outcome (P<0.05). Among these factors, initial hematoma volume was a borderline prognostic factor (odds ratio [OR], 0.951; 95% confidence interval [CI], 0.904-1.001; P=0.054), whereas initial GCS score was a significant prognostic factor (OR, 2.737; 95% CI, 1.371-5.465; P=0.004), in the multivariate analysis.

CONCLUSION

Initial GCS score and hematoma volume were important prognostic factors of clinical outcome in patients with spontaneous ICHs who underwent navigation-assisted drainage. Such factors should be carefully considered before patients are treated with navigation-assisted hematoma drainage.
